` LUBRICATOR.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed April 3, 1906. Serial No, 309,656.

To all whom t may concern:

Be it known that I, EVERITTE K. BARNES, a' citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

The object of this invention is to construct a force feed lubricator adapted more especially for motor vehicles.

In the accompanying drawings. Figure l is a lengthwise vertical section through the operative parts. Fig. 2 is a transverse vertical section of the casing, the operative parts not sectioned. Fig. 3 is a transverse vertical Figs. 4, 5, 6 and 7 are similar vertical sections on dotted line l) Fig. 1, showing the intake and discharge openings, and the four positions of the valve in making a coin'plete revolution. Fig. 8 is an isometrical representation of one end of the piston operating bar. Fig. 9 is an isometrical representation of the series of valves. Fig. 1.0 is an isometrical representation of one of the piston supports.

The casing supporting the operative parts of my improved lubricator comprises the back 1, front 2, ends 3 and top 4. The top supports a series of bushings 5, 6, 7, 8, 9 and 10, and located the same distance from thel front edge of the casing.

The front of the casing has an opening 11.

. which is covered by a section of glass 12.

Within the casing is secured a support 13 for the valves and pistons, and said support is located in the front lower angle of the casing. This support has a lengthwise circular hole 14 extending throughout its length and also has a series of vertically arranged cylinders 15,`16,17,18,19 and. 29. The openings 21 in these cylinders communicate with the circu-A lar hole 14 in the support 13.

The six bushings guide six piston supports 22, 23, 24, 25, 26 and 27, and as they are all of the same construction a description of one will suffice, and reference will be made to the support 22 shown at Fig. 10.

' The upper section 28 of the support is cylindrical and fitted to slide vertically in one of the bushings and has an internal` screwthreaded opening 29. The lower section 30 is also cylindrical and has an internal screwthreaded opening 31 within which is turned a piston 32. A jam-nut 33 turned against the lower end of the lower section prevents he piston from turning.

The section 34 intermediate or connecting the upper and lower sections has a rectangular opening 35 extending in the direction of the length of the section. The supports 23, 24, 25, 26 and 27 have pistons 36, 37, 38, 39 and 40 connect-ed thereto, one for each support, and each piston is located in its proper cylinder.

A bar 41 in this instance is square in crosssection, and is located in the rectangular openings of the supports 22, 23, 24, 25, 26 and 27, and has its ends 42 rounded.

Within the screw-threaded openings ofeach of the upper supports 22, 23, 24, 25, 26 and 27 are located screws 43, 44, 45, 46, 47 and 48 one for each support which extend within the rectangular openings of the supports.

Within the circular opening 14 of the support 13 is located a rotatable valve shaft 49. To this valve shaft 49 is secured a wormwheel 50. A cross-shaft 51 is supported, in bearings 52 in the front and back walls of the casing, and is rotated by a belt connection with the pulley 53 connected to it. This cross-shaft supports a worm 54 which meshes with the worm-Wheel 50, and the rotations of the worm will impart a rotary movement to the Worm-wheel, and it in turn will rotate the valve-shaft 49. From each end ofthe valveshaft 49 extends a wrist-pin 55.

Two links 56 and 57 have their lower ends connected to the wrist-pins of the valveshaft and their up er ends connected to the rounded ends 42 o the bar 41, thereby forming a connection between the valve-shaft and bar. As the valve-shaft rotates it will impart a bodily vertical movement to the bar 41. The valve-shaft has its outer surface formed with valve grooves for each piston, and a description of the grooves for one piston will answer, the grooves for all the pistons being indicated by corresponding numerals.

The annular groove 58 is located beneath the piston, so that, as the valve-shaft rotates, the piston will be in continuous communication with the groove. Parallel with this annular groove 58 is formed a partial annular groove 59 extending not quite half way around the outer surface of the valve-shaft. A groove 60 extends in the lengthwise direction of the valve-shaft and connects or forms a communication between the annular groove 58, and the partial annular groove 59. This partial annular groove is so located that during the rotation of the valve-shaft it will IIO alternately form communication with the intake opening 61, and discharge opening 62. Each ofthe discharge openings Y62 have a sight feed 63 communicating with it.

The object in vertically :moving the bar 4l is to impart a reciprocating movement to the pistons, this is accomplished by the bar seating against the lower end of the rectangular openings of the supports 22, 23, 24, 25, 26, and 27 and exerting its force against the screws 43, 44, 45, 46, 47 and 48 during its upward movement, and when the screw 43 is in the position shown in connection with support 22, the full up and down movement of the bar will be transmitted tothe piston 32.

When the screw 40 is in the position shown in connection with the support 27 the movements of the bar will not reciprocate the piston, as it can move without engaging either the lower end of the rectangular opening or the screw.

When the screws are in the positions shown in connection with the supports 23, 24, 25 and 26, the pistons thereof will be more or less reciprocated, so that, by means of the screws, the extent of the reciprocation of the pistons can be varied.

During substantially the full upward stroke of the piston the partial annular groove 59 will be in communication with the intake opening 6l, and during substantially the full downward stroke of the piston, said partial annular groove will be in communication with the discharge opening 62. At Figs. 4, 5, 6, and 7 are shown the positions of the partial annular groove 59 during a revolution of the valve shaft. Fig. 4, shows the position of the groove when the piston is starting up. Fig. 5 shows the position of the groove when the piston is halfway up. Fig. 6, when the piston is full up and Fig. 7 when the piston is half way down.

In use, lubricating oil is placed in the casing, and during the upward stroke of the piston, oil will be drawn into the cylinder through the partial annular groove 59, the lengthwise groove 60 and the annular groove 58. 'During the downward movement of the piston oil will be forced out through the same grooves into the discharge opening 62 and through the sight feed to the parts to be lubricated.

The same amount of oil drawn in by the piston will be forced out during the donnward movement, this amount being regulated by the screws.

By this arrangement the operator can regulate the quantity of oil fed to lubrieai any particular part.

I claim as my invention.

l. In a lubricator, the combination of an oil reservoir, a cylinder, a piston for the cylinder, a rotatable valve for the cylinder, comprising a cylindrical shaft, there being an annular groove formed in the periphery of the shaft, a partial annular groove formed in the periphery of the shaft, and a groove extending in the lengthwise direction ol the shaft and forming a communication between the annular groove and partial annular groove.

2. In a lubricator, the combinatioii of an oil reservoir, a cylinder, a piston for the cylinder, a rotatable valve for the cylinder eoinprising a cylindrical shaft, there being an annular groove formed in the periphery of the shaft, a partial annular groove formed in the periphery of the shaft and a groove extending in the lengthwise direction of the sha1 t and forming a communication between the annular groove and partial annular groove, means for rotating the shaft and `means for reciprocating the piston.

3. In a lubricator, the combination oi' an oil reservoir, a cylinder, a piston for the cylinder, a rotatable valve for the cylinder coinprising a cylindrical shaft, there being an annular groove formed in the periphery olI the shaft, a partial, annular groove formed in the periphery of the shaft and a groove extending in the lengthwise direction of the shaft and forming a communication between the annular groove and partial annular groove, a connection between the shaft and piston, and means for rotating the shaft and reci procating the piston.
